GAS OR ELECTRIC LIGHT EXTENSION-FIXTURE.

Specification of Letters Patent. I

Patented Ma 7, 1912.

Application filed July 26, 1911. Serial No. 640,629.

To all whom it may concern:

Be it known that I, CONRAD M. PITEL, a citizen of the United States, residing at Meriden, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Gas or Electric Light Extension-Fixtures; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification and represent, in

Figure 1 a side view of an extension fixture constructed in accordance with my invention. Fig. 2 a broken sectional view of dome inclosing'one or more lights which may be raised or lowered with respect to the other part of the fixture, the object being to provide a suitable gas-way or conduit for electric wires from the point to which the chandelier is attached, to the burners; and the invent-ion consists in the construction hereinafter described and particularly recited in the claims.

In carrying out my invention I form a nipple 2 which is adapted to be secured to a gas-supply pipe in the ceiling with a thread ed opening 3 in one side into which is turned the upper end of a gas-way 4 the lower end of which opens into a head 5. The nipple and head are connected by a bar 6 which forms a support for the shaft 7 projecting from the gas-way for a spring-drum 8 which contains a coiled spring 9 in the usual manner for extension fixtures. Connected with the head 5 and with the arm-box 10 is an outer tube 11 and also connected with the head 5 and the arm-box 10 is an inner tube 12 the space between the inner and outer tubes forming a gas-chamber leading to the arm-box which supports arms 13 more or less innumber to which the stationary lights are attached. W'ithin 'theinner tube is an extension tube or rod 1-1 the upper end of which is attached to a. cord, wire or chain 15 wound about the drum 8, and to the lower end of this extension-rod 14: a shade support 16 is attached, and also a threaded plug 17 to which a lighting fixture of any desired type may be connected.

To prevent the extension rod or tube from turning, it is preferably made hexagonal, and attached to the lower end of the inner tube which projects below the arm-box 10 is a nut 18 formed in its lower end with. a hexagonal opening through which the extension rod or tube passes and this nut is held against turning on the inner tube by a set screw 19. Between the drum 8 and the bar 6 is a friction spring 20, and the end of the shaft 7 is split to receive a key 21 which extends through a clearance slot in the bar into engagement with the spring and which may be crowded against the spring with more or less pressure by means of a nut 22 which is turned onto the threaded end of the shaft 7.

It will be noted that the nipple 2 may be turned with respect to the upper end of the gas-way 4 and the upper end of the bar 6 so as to form a swivel which permits the fixture to be turned slightly to bring it into vertical position. Gas entering the nipple 2 passes through the gas-way 4 and into the space between the inner and outer tubes and thence to the arms 13, and in one of the arms is a cock-connection 23 to which a flexible pipe 24 may be attached, this pipe leading to the burner within the shade, and this pipe may be supported when the drop fixture is raised by means of hooks 25 secured to the lower edge of the shade or to the shade band if one is employed. It will thus be seen that the fixture is provided with a drop light and one in which gas may be conducted to the arms without interfering in any way with the operation of the suspension device. It will be apparent that wires may be conducted through the gasways and thence through the arms to the burners. It is also obvious that my invention is applicable to fixtures consisting of a dome and without arms.

1. An extension fixture comprising inner and outer tubes forming a gas-way between them, an extension rod or tube within the inner tube, a spring drum, connection be-- tween the extensi0n rod or tube and the drum, a supporting-nipple and a gas-way connecting the nipple with the outer tube, a. drop-light fixture secured to the lower end of the extension rod or tube, and a flexible conducting connection between a stationary part of the fixture and the dropflexible conducting connection between a stationary part of the fixture and the droplight.

3. An extension fixture comprising inner and outer tubes forming a gas-way between them, an extension-rod or tube within'the inner tube, a spring drum, connection between the extension rod or tube and the drum, a supporting nipple and a gas-way connecting the nipple with the outer tube, a drop-light fixture, including a shade or shade band, swivelly connected with the outer end of the extension-rod or tube, and a flexible conducting connection from a stationary part of the fixture through the shade or band to the drop-light.

4. An extension fixture comprising inner and outer tubes forming a gas-way between them, an extension rod or tube within the inner tube, a supporting nipple, a. gas-way swivelly connecting the outer tube with the nipple whereby the fixture may be swung into a vertical plane, a spring drum supported by the gas-way, connection between the extension rod or tube and the spring drum, and a drop-light fixture at the lower end of the extension rod or tube.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
